300]? FOR SILOS OR THE LIKE.

Specification of Letters Patent.

Application filed. December 10, 1913.

Patented Ma r 1.2, 1914.

Serial No. 805,714.

To all whom it may concern Be it known that I, CHARLns E. MARTIN, a citizen of the United States of America,

.residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Roofs for Silos or the like, of which the following is a specification.

This invention relates to certain new and useful improvements in roofs for silos and the like, and the primary object thereof is to provide a roof which is self-sustaining and which eliminates braces or other suspension means to thereby increase the holding capacity of the silo, by enabling the space, usually occupied or taken up by the roof suspension means, to be used for storage of an additional amount of silage.

Further, the invention aims to provide a roof which can be easily and readily assembled, and which when in operative position will provide a rigid and effective structure.

The invention consists essentially in an approximately truncated cone-shaped body which is formed in sections, the latter being secured at their upper ends to a ring-like part combined with a crown which is also secured to said ring-like part in order to effectively relate the parts against movement, and to also enable the structure to be easily and quickly assembled.

In the drawings: Figure l is a side eleva tion, the door being omitted and the crown of the roof partly broken away; Fig. 2 is an interior side elevation, parts being omitted and other parts being shown in fragment; Fig. 3 is a fragmentary detail view showing the manner of hinging the door; Fig. 4: is a section taken on the line 4- 1 of Fig. 2; Fig. 5 is a section taken on the line 5-5 of Fig. 2; and Fig. 6 is a perspective view of one of the brackets forming a part of the means for securing the crown of the roof in position.

The silo body 1 may be of any preferred form and at its upper end supports the body 2 of the roof, the body 2 in turn supporting the crown 3, which latter has a conventional type of ventilator 41 secured thereto.

The body 2 of the roof is of truncated cone-shape and is formed of a series of tapered sections 41, preferably formed of corrugated metal, the upper ends of which sections fit in the corner of an angle-bar ring or band 5, as clearly depicted in Fig. 5 of the drawings. Each section 1 has two or more straps 7 secured to its upper end portion on the inner face thereof, which straps project above the extreme upper end of the section and are bent over the angle-bar ring or band so as to conform thereto, the straps being formed of flexible or pliable material for the purpose mentioned. The free outer ends 8 of the straps are disposed to be engaged by the free upper edges of the sections to which they are attached so as to hold said. ends 8 against movement, as depicted in Fig. 5 of the drawings. A pair of clips 9 are secured to the inner face of each section 1 and project below the lower end of same, the clips being offset to provide shoulders or abutments 10 which seat on the upper free edge of the body 1 so as to thereby assist in holding the sections against downward movement. The lower ends of the clips 9 are suitably secured to the silo body 1, by any suitable fastening means 10'. The sides of adjacent sections overlap and are secured together by rivets 11 or other approved fastening means. The crown of the roof is also formed of tapered sections which are corrugated and overlap at their adjacent sides and are secured rigidly together by riveting, or the like. For the purpose of rigidly connecting the crown to the body of the roof, a series of hangers 12 are rigidly secured to the under face of the crown, and have hooks 13 borne by their lower ends, which hooks receive and support the horizontal portions 14 of brackets that have their ends formed with hooks 15 which latter receive the vertical member 16 of the angle bar ring or band 5. By this means, the crown is rigidly secured to the roof body and is firmly anchored in position so as to resist wind and rain, etc.

A door or closure 17 is placed over the opening 18 which latter provides access to the interior of the silo, the lower end of the door resting on the upper end of the body 1, while its upper end has a hook shaped finger 19 secured thereto, which finger engages on top of the ring 5 as shown in Fig. 3 of the drawings to thereby provide a hinge connection for the door. The lower end of the roof body 4-. projects beyond the peripheral wall of the silo body, and the lower end of the crown 3, likewise extends beyond the periphcry of the band 5 so as to provide weatherproof joints.

In assembling a silo in accordance with the present invention, a pair of the sections 4 are supported in diametrically opposed relation on the silo body 1 after which the ring or band 5 is supported from said pair of sections in the manner 'hereinabove described. The remaining sections are then placed in position and secured until the roof is completely i'orined, space being left toprovide the door opening 18 above described.

hat is claimed is:

1. A silo roof including. a sectional body, an angle-iron ring at the upper end of the body, the sections of the body having their upper ends engaged in the angle of the angle-iron ring, straps secured to the sec-- tions and bent around said ring-and a crown overlying the ring and secured thereto.

2. A silo roof including a sectional body, an angle-iron ring at the upper end of the body, the sections of the body having their upper ends engaged in the angle of the angle-iron ring, flexible straps secured to the sections and being bent around the ring and having their free ends engaged with the upper ends of the sections, and a crown secured to the ring.

3. A silo roof including a sectional body, an angle-iron ring at the upper end of the body, the sections of the body having their upper ends engaged in the angle of the angle-iron ring, flexible straps secured to the sections and. being bent around the ring and having their free ends engaged between the under face of the horizontal part of the angle-iron ring and the upper ends of the sections to thereby secure said strap ends against movement, and a crown secured to the ring.

41:. In a silo roof, a body member, a ring secured to the upper end thereof, a crown seating on the ring, hangers depending from the crown, and brackets connected to the hangers and engaged with the ring.

5. In a silo roof, a body member, an angle-iron ring secured to the body member, a crown seating on the ring, hangers depending from the crown, and brackets having central portions secured to the hangcrs and ends of hook-shape which engage the under edge of the vertical part of the ring.

(3. In a silo roof, a sectional body vmember, an angle-iron ring at the upper end of said 1ne1nber,'-the sections of the body member having their-upper ends engaged in the angle of said angle-iron ring so that the horizontal part of said ring overlies said upper ends of the sections, and a crown which seats 011 said horizontal ring and projects therebelow.

In testimony whereof I afiix my signature in presence of two witnesses.
